Plug options with C.O.P?
Im running the aem v2 twin fire, last year I was running ngk iridium plugs. The plugs I want to use I cant because there a non resistor plug. So my question is what are you other big hp guys using besides the expensive iriduim plugs? #9,10 plugs.
thanks
thanks

Re: Plug options with C.O.P?
I believe they do.... NGK IFR9H-11
It's the "laser iridium" plug
Looks like it should work. It's used on the 2002-2006 Honda RVT1000R RC51. Badass bike btw, but they still can't hang with my Ducati 1098S. lol
It's also a bit more expensive than the IK27

Why doesn't someone call NGK on their toll free 800 # and ask for Tech Support and talk with the experts, instead of some guy on a Ducati.
There must be a $2.00 plug out there that will work. After all, it's only going to be there for a 1/4 mile.

I got that NGK number after only 2 min of reasearch. I'm sure there are others out there that will work fine. Just takes time to research.

Re: Plug options with C.O.P?
you can turn down an ngk tip on a lathe to make it work...
also i believe the aem coils accept the cheaper ngk plugs as well, if i remember correctly reading some of bisi's posts, but overall, just not as good as a coil as the cbr ones

For those of us that replace them after every run and not getting new ones for free. Cheap and works for one pass is a better option.

Re: Plug options with C.O.P?
Aem told me I had to use a resistor plug, a non resistor plug would cause to much interference. So ya looking for a resistor plug that would work that is not 6-8 each. I will try to call ngk asap, just thought I would see what everyone elso was using for with a cdi or other ignition that requires a resistor plug.

Hint to you guy's that haven't figured it out yet. Weld a 5/8 spark plug socket to a 6" extension.

Re: Plug options with C.O.P?
This is just going off a website that sells a ton of sparkplugs.... haha
These are all resistor plugs
NGK BKR8EIX - Heat Range 8 - $8.48
NGK BKR9EIX - Heat Range 9 - $8.48
Denso K24PR-U11 - Heat Range 8 - $2.89
Denso K24PR-ZU - Heat Range 8 - $5.72
Denso Q27PR-ZU - Heat Range 9 - $5.72
I don't have my other books to look up other manufacturers. I have never used those particular denso plugs I always just run the iridiums, but you wanted cheap so here it is.

Re: Plug options with C.O.P?
You will not find a copper/cheaper alternative in a 9 or 10 range that is a resistor type, been down this road many years ago.
This was a minor issue when running the AEM CDI boxes back in the day for us, other than them just burning up. LOL
When we switched to the M&W stuff no issues at all running the R5671A-X plugs, these are the plugs you will find most racers use if they can use a non-resistor plug. If they have to run a resistor type plug or a plug that has to have a removable "terminal" you will see most run the Denso IK27 or colder plug.
